Russia doesn't win a nuclear war, and they know this. It won't happen.
They also know that they can have peace if they leave Ukraine, so France joining the war is not an existential threat.
Honestly, we're more likely to get nuclear war if we cede this kind of power to them. Ignore them and there won't be a reason for nuclear proliferation.
I agree. I just thought the image was provocative. I can't draw very well so I wrote it. France was actually one of the more aggressive advocates for nuclear weapons in the event of world war 3 during the Cold War. So in my head I see a French soldier with a cigarette in his mouth. He's staring dead eyed into the East and his hand is resting on a safety cover over a red button.
